Objective To investigate the inhibitory effect of paclitaxel on rat graft arteriosclero- sis and the mechanism.Methods The rat abdominal aortic allograft model was used.All rats were divided into three groups:isograft control group (Wistar to Wistar),allograft group (Wistar to SD) and allograft paclitaxel-treated group (Wistar to SD).Rats in allograft paclitaxel-treated group re- ceived paclitaxel (2 mg?kg~(-1)?d~(-1)) from the operation day to post-operative day 14 and others received same dosage of vehicle (0.9% normal saline).Animals were sacrificed and the grafts were harvested at 30th day after operation.Intimal proliferation was studied by light microscopy.The apoptosis of vascular smooth muscle cells (VSMCs) was detected by transmission electronic microscopy and termi- nal deoxynucleotidyl transferase biotin nick end-labeling (TUNEL) method.Results Morphological analysis showed that grafts had no change after operation in isograft control group,but in allograft group intimal proliferation,inflammatory cells infiltration in neointima and adventitia and stenosis of allografts were obvious.After treatment with paclitaxel,there was a significant decrease in intimal proliferation,inflammatory cells infiltration and stenosis.Apoptosis index of VSMCs was higher in the allograft paclitaxel-treated group than other groups.Conclusion Paclitaxel can inhibit intimal pro- liferation in aortic allografts and prevent the graft from arteriosclerosis possibly by inducing the apoptosis of VSMCs.

Objective To observe endoplagmic reticulum stress in bone tissue of fluomsis rats and further explore the pathogenesis of skeletal fluorosis.Methods 48 Wistar rats were divided into 4 groups according to their body mass.The control and low.calcium group were fed with normal diet(0.79%calcium)and low-calcium diet(0.79%calcium)respectively,and both drank tap water(sodium fluoride concentrations＜1 mg/L).High fluoride and low.calcium plus high-fluoride groups were fed with normal diet(0.79%calcium)and low-calcium diet (0.79%calcium)respectively,and both drank tap water containing sodium fluoride(sodium fluoride concentrations 221 mg/L).During experimental period,rats were measured body mass once a week with a stand diet and water available ad libiturn.The experimental period was 3 months.The biochemical techniques were used to test the indicators of oxidative stress and ALP in seFum of fluorosis rats.The total RNA was extracted from the one side of the femur,and the transcription level of Bip,Xbp1,CHOP and PDI were investigated by reverse transcription polymerase chain reaction(RT-PCR).Results The level of MDA in serum of low-calcium plus high-fluoride group wag higher than that of the control[(14.74±3.11)μmol/L vs(10.15±1.96)μmol/L,P＜0.05];the activity of GPx was ma~edly higher in hish-fluoride group compared with the control[(3.87±0.41)×103 U/L vs(2.85± 0.55)×103 U/L,P＜0.05];the level of uric acid in sel'um was significantly lower both in high-fluoride group and low-calcium plus high-fluoride group compared with the respective control and the low-calcium group[(73.95± 9.52)μmol/L vs(110.43±25.48)μmol/L,(54.32±22.09)μmol/L vs(101.71±17.01)μmol/L,P＜0.05]. The activity of ALP wag obviously higher in low-calcium plus high-fluoride group compared with the control [(24.77±4.57)×103U/L vs (12.91±3.97)×103U/L,P＜0.01)].The mRNA expression of Bip/GAPDH in bone tissue was markedly higher in bone of high-fluoride group and low-calcium plus high-fluoride group compared with the control(1.38±0.24,1.35±0.12 vs 1.14±0.06,P ＜ 0.05). The expression of Xbp1/GAPDH in bone tissue significantly increased in low-calcium plus high-fluoride groups compared with the control and the low-calcium group (1.48±0.20 vs 1.02±0.25,1.07±0.25,P ＜ 0.05 or ＜ 0.01);and CHOP/GAPDH in bone tissue significantly increased in low-calcium plus high-fluoride groups compared with the control(0.84±0.18 vs 0.52±0.07,P ＜ 0.05 ). Conclusions Accelerated osteogenetic action is seen in fluorosis rats,accompanied by oxidative stress and bone endoplasmic reticulum stress,which is likely involved in the pathogenesis of skeletal fluorosis.

OBJECTIVE: To understand the assessment on the criminal responsibility of drug-induced mental disorders and judicial experts' opinions. METHODS: The judicial experts from institutes of forensic psychiatry in Shanghai were selected. They were asked to finish a self-made questionnaire of assessment on the criminal responsibility of drug-induced mental disorders by letters and visits. RESULTS: Most of experts knew the special regulation, "not suitable for evaluation" towards the criminal responsibility of drug-induced mental disorders of the guideline promulgated by Ministry of Justice. Before and after the guideline was issued, no expert made a no-responsibility opinion in such cases. After the guideline was issued, some experts made a full-responsibility or limited-responsibility opinion in such cases. There was a little disagreement among the experts in the case that the crime was unrelated with mental symptoms or the criminals used drugs even though he knew it could induced insanity. But there were still many obvious disagreements among experts in the case that crime was related to such symptoms and person was no ability to debate. Most experts agreed to settle the disagreements with improved legislative perfection. CONCLUSION Most experts are not strictly complying with the assessment guidelines during their practice, and there is still an obvious disagreement towards the criminal responsibility of drug-induced mental disorders.

OBJECTIVETo evaluate the efficacy and safety of tiaogan Lipi Recipe (TLR) in treating non-alcoholic fatty liver disease (NAFLD) patients of Gan stagnation Pi deficiency syndrome (GSP-DS).

METHODSA randomized, double blind, placebo-controlled clinical trial was performed. Totally 99 NAFLD patients of GSPDS were randomly allocated into two groups, 66 patients in the treatment group (treated with-TLR, one dose per day) and 33 patients in the control group (treated with placebos, one dose per day). The therapeutic course for all was 12 weeks. All patients received lifestyle interventions including moderate aerobic exercise, moderate caloric restriction, and dietary changes. Clinical symptoms, CT indices, liver functions and blood lipids were observed before and after treatment.

RESULTSAfter 12 weeks of treatment, the total score of clinical symptoms decreased in the two groups (P <0. 01), and it was lower in the treatment group than in the control group (P <0. 05). Liver/spleen CT ratio increased in the treatment group (P <0. 01), and it was higher in the treatment group than in the control group (P <0. 01). After treatment levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) all decreased in the treatment group (P <0. 05, P <0. 01), while levels of ALT decreased in the control group (P <0. 05). Besides, all the 3 levels mentioned above were lower in the treatment group than in the control group (P <0. 05). Levels of total cholesterol (CHO) and triglyceride (TG) decreased in the two groups (P <0. 05), and they were lower in the treatment group (P <0. 05). Total effective rates of TCM syndrome, abdominal CT, liver functions, and blood lipids were 79. 69% (51/64 cases), 54. 69% (35/64 cases), 67. 65% (23/34 cases), and 67. 39% (31/46 cases) in the treatment group, while they were 56. 25% (18/32 cases), 25. 00% (8/32 cases), 33. 33% (6/18 cases), and 55. 56% (10/18 cases) in the control group. All were superior in the treatment group (P <0.05, P <0.01, respectively).

CONCLUSIONTLR combined with lifestyle intervention could safely and effectively improve clinical symptoms of NAFLD patients of GSPDS, elevate liver/spleen CT ratios, and play a role in liver protection, anti-inflammation, and lowering blood lipids.

The purpose of the present work is to observe whether Tau protein Ser202/Thr205 is hyperphosphorylated in braintissues of diabetic mice and to study the effect of App17 peptide. Mouse diabetic model was produced with streptozotocin, andApp1 7 peptide as a treatment was injected subcutaneously into diabetic mice. Four weeks later, fixative was injected intravascu-larly into the mice, the brain was removed and crystat sections prepared. Immunohistochemical staining was done with AT-8. Inthe brains of diabetic mice positive AT-8 reacting neurons were numerous, darkly stained, and widely distributed in retrosplenialgranular cortex, hippocampus, thalamus et al. , while in normal mice and App17 peptide-treated diabetic mice positive cells werescarce and poorly stained. Tau protein is hyperphosphorylated at Scr202/Thr205 site and widely distributed in the brains of dia-betic mice, while App17 peptide can normalize the expression of AT-8 positive cells.

Objective Through the observation on the distribution of hyperphosphorylated Tau,to investigate the connection between hyperphosphorylated Tau and learning, memory tasks. Furthermore, the treatment of App17 on brain tissues of diabetic mice. Methods Diabetic model mouse was produced in the use of streptozotion and App17 peptide as a curative was injected subcutaneously. Four weeks later, removed the brains. Immunohistochemical stainning was done with AT\|8, Tau\|1, again with Tau\|1 antibody after dephosphorylation. Results In the brains of diabetic mice positive AT\|8 reacting neurons were widely distribution in retrosplenial granular cortex, hippocampas, thalamus et al, the cytoplasm was darkly stained, while in normal mice and App17 peptide\|treated diabetic mice positive cells were localized in retrosplenial granular cortex, however, in hippocampas and RSG area, the cytoplasm were poorly stained. Conclusion Hyperphosphorylated Tau is widely expressed in brains of diabetic mice. App17 peptide can improve the hyperphosphorylated Tau in brains of diabetic mice, therefore, it may improve learning ability and memory.\;

OBJECTIVETo compare the effect of transurethral resection of the prostate combined with endocrine therapy (TURP + ET) with that of αlA-blockers combined with ET ((αlA-b + ET) in the treatment of bladder outlet obstruction (BOO) in patients with advanced prostate cancer (PCa), and to investigate the safety of the TURP + ET for the treatment of PCa with BOO.

METHODSWe retrospectively analyzed 63 cases of PCa with BOO, 28 treated by αlA-b + ET and the other 35 by TURP + ET. We obtained the residual urine volume (RV), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life score (QoL) before and after treatment along with the overall survival rate of the patients, followed by comparison of the parameters between the two methods.

RESULTSAt 3 months after treatment, RV, IPSS, and QoL in the TURP + ET group were significantly decreased from (137.8 ± 27.6) ml, (22.3 ± 3.6), and (4.2 ± 0.8) to (29 ± 13.6) ml, (7.8 ± 2.1), and (1.6 ± 0.5) respectively (P < 0.05), while Qmax increased from (5.6 ± 2.1) ml/s to (17.6 ± 2.7) ml/s (P < 0.05); the former three parameters in the αlA-b + ET group decreased from (133.6 ± 24.9) ml, (21.5 ± 3.2), and (4.7 ± 1.1) to (42 ± 18.3) ml, (12.8 ± 2.6), and (2.5 ± 0.7) respectively (P < 0.05), while the latter one increased from (6.3 ± 2.4) ml/s to (11.7 ± 2.3) ml/s (P < 0.05), all with statistically significant differences between the two groups (P < 0.05). The overall survival rate of the TURP + ET group was not significantly different from that of the αlA-b + ET group (51.4% vs 46.4% , P > 0.05).

CONCLUSIONTURP + ET is preferable to αlA-b + ET for its advantage of relieving BOO symptoms in advanced PCa without affecting the overall survival rate of the patients.

OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.

METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.

RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).

CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.
